post #1 of 5
Thread Starter 
hi i have a gtx 660 from evga and i unlocked the bios yesterday and when i ran some benchmarks i saw lower scores than before and then i started monitoring the performance and i saw that when i ran nvidia hair demo my core clock was at 1241 mhz and the power usage was 90% with 99% gpu load and then i ran heaven 4.0 and saw that the core clock was at 1111mhz but when the power usage went 106% it throttled back to 1045 is this normal because i wasn't expecting this after setting the voltage to 1212 what should i do? plz help

the temps. are always under 65

there is a 660 (non ti) thread where you can post this; however, welcome to ocn.

In regards to solving your issue... Are you manually setting the voltage to 2.212mv with the help of an overclocking application? And what clocks are you running at?

Don't manually set the voltage to 1.212mv, kepler cards are different from fermi, the card does not need you to do that and it will throttle more if you try to manually set the voltage (from my experience). Also, why did you down-clock the card?

because it was unstable
